Results messages in "results output" window

Dear friends,

I've been using PgAdmin 12.0.0 released on Jan 6, 2015, compiled in my
Ubuntu 14.04 x64.
Nothing noticiable in terms of use (actually, there are few known bugs,
but they don't bug me anyway).

I would like to know if there is any change to enable processing results
to appear in Results output window when running a script the this one:

begin transaction;
update mytable set factor_xy = 10 where factor_xy = 15 and nature_id = 4;
commit transaction;

Today I get the following output:

[QUERY ] begin transaction
[QUERY ] update mytable set factor_xy = 10 where factor_xy = 15 and
nature_id = 4
[QUERY ] rollback transaction

I would like to get something like:

[QUERY ] begin transaction
*0 rows changed.*
[QUERY ] update mytable set factor_xy = 10 where factor_xy = 15 and
nature_id = 4
*16 rows changed.*
[QUERY ] rollback transaction
*0 rows changed.*

Is there any configuration I can change to get this?
